Additional Details

The JS-12-K typically operates with a coil voltage of 12VDC. The contact rating, which specifies the maximum voltage and current the relay can switch, is an important parameter to consider. The relay is typically available in a through-hole package for easy mounting on printed circuit boards. The operating temperature range is generally between -40°C and +85°C. The coil resistance and pull-in voltage are also important parameters for proper relay operation. The insulation resistance between the coil and contacts is typically very high, ensuring isolation and safety.
